Hi, I've configured the all.yml like this: grep -v "^#\|^$" ceph/ceph-ansible-playbooks/ceph-ansible-stable-4.0/group_vars/all.yml --- dummy: nautilus: 14 cluster: ceph mon_group_name: mons osd_group_name: osds mgr_group_name: mgrs configure_firewall: False centos_package_dependencies: - epel-release - libselinux-python ceph_origin: repository ceph_repository: community ceph_mirror: http://hk-repo-2001/repo/ceph/ ceph_stable_key: http://hk-repo-2001/repo/ceph/release.asc ceph_stable_release: nautilus ceph_stable_redhat_distro: el7 monitor_interface: bond0 ip_version: ipv4 public_network: 10.121.58.0/24 cluster_network: 192.168.58.0/24 osd_objectstore: bluestore dashboard_enabled: False I'd like to install from our repo server, but when it wants to install at this step it complains about can't reach the epel repository: TASK [ceph-common : install redhat ceph packages] ******************************************************************************************************** FAILED - RETRYING: install redhat ceph packages (3 retries left).

I've tried to change on the hk-ceph-2c07 in the epel.repo file uncomment baseurl and comment out metalink, cleaned yum ... but nothing helped, I guess something is wrong with my internal link. When I try to install something from epel repo on the server, I can, but via ansible I can't. I'd like to deploy ceph with ansible user, the rights are correct. Here is the hosts file for the playbook: [all:vars] ansible_ssh_user=ansible ansible_become=true ansible_become_method=sudo ansible_become_user=root [mons] hk-cephm-2007 hk-cephm-2008 hk-cephm-2009 [mgrs] hk-cephm-2007 hk-cephm-2008 hk-cephm-2009 [osds] hk-ceph-2c07 hk-ceph-2c08 hk-ceph-2c09 hk-ceph-2c10 Why is the repo error or network unreachable?
